PIPE-TONGS.

5PECIFICATION forming part of Letters Patent No. 331,456, dated December1, 1885.

Application filed October 1, 1885. Serial No. 178,772. (No model.)

To aZZ whmn it may concern:

Be it known that I, HENRY F. W. SOHST, of the city and county of SanFrancisco, and State of California, have invented an Improvement inPipe-Tongs; and I hereby declare the following to be a full, clear, andex act description thereof.

My invention relates to that class of pipe tongs in which a fixed jaw ismade integral with the stock or handle, and a swinging jaw is pivoted tothe fixed jaw or to the stock; and my invention consists in the novelconstruction of the pivoted jaw, its arrangement with relation to thefixed jaw, and a spring for the saidpivoted jaw, all of which I shallhereinafter fully describe.

The object of my invention is to provide a simple and effectivepipe-tongs adapted to receive different sizes of pipes and to grip themwithout danger of slipping.

Referring to the accompanying drawings, Figure 1 is a perspective viewof my pipetongs. Fig. 2 is an elevation showing the tongs when not inuse.

A is a handle or stock, and B is the curved or hooked fixed jaw formedon one end of said stock.

0 is the pivoted or .swinging jaw. This is longitudinally slotted, sothat it has two separated side pieces, and these are united by atie-piece, c. The face of this jaw is convexed and is preferablytoothed, as shown. It is pivoted to the stock by the pin D, which islocated at or near the point where the handle or stock merges into thefixed jaw. The pivoted jaw is adapted to fit over the fixed jaw, itssides embracing said jaw until limited by the tie-piece c,bearing on theinner surface of said jaw. A spring, E, bearing on the tiepiece, holdsthe pivoted jaw normally to the positionjust described. I provide thehandle or stock A with a socketed extension,a,secured by a cross-pin, a.This is intended to be used in case a greater leverage is needed. Theccnterof pivotal action of thejaw O is so located that the curve of theface of said jaw rapidly and positively moves past and back of the curveof the fixed jaw, thereby causing the jaw O to grip the pipe withcertainty and firmness, and by reason of fitting down over 1 the fixedjaw any size of pipe may be inserted. The spring renders the tongs easyof application, as it starts the jaw O to take hold immediately andholds it to its grip, all that is required being to hold the jaw backwhile fitting the tongs on the pipe.

I am aware of the existence of tongs having a fixed and a pivoted jaw;butI am not aware that the pivoted jaw has ever been so slotted as toadapt it to fit over or embrace with its entire length the fixed jaw.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A pipe; tongs comprising a handle or stock, a fixed curved or hookedjaw on said handle or stock, and a longitudinally-slotted or two-sidedjaw having a convexed face and pivoted to the handle or stock, said jawbeing adapted to fit down on each side of the fixed jaw, substantiallyas described.

2. A pipetongs comprising a handle or stock, a fixed curved or hookedjaw on said handle or stock, a pivoted or swinging longitudinallyslottedor two-sided jaw having a convexed face, and a tie-piece between thesides of said jaw to limit its movement over the fixed jaw,substantially as described.

3. A pipe -tongs comprising a handle or stock, a fixed curved or hookedjaw on said handle or stock, a longitudinallyslotted or two-sided jawhaving a convexed face and pivoted to the handle or stock, said j awbeing adapted to fit down over the fixed. jaw, and a spring bearing onthe pivotedjaw, substantially as described.

4. A pipe-tongs consisting of the handle or stock A, the fixed curved orhooked jaw B on its end, the longitudinally slotted or twosidedconvexed-faced jaw O, the pin D, pivoting said jaw to the handle orstock, the tie piece c,between the sides of said jaw, and the spring E,bearing 011 the tie-piece, substantially as described.

In witness whereof I have hereunto set in hand.

HENRY F. W'. SOHST.
